I have to admit, I find this idea much more interesting than a basic VC 
sustain level (since I can see little use for increasing the sustain level 
over time). I know the old Digisound (it just occurred to me how strange that 
name sounds -- "the sound of digital, with the affordability of analog!") 
line had a CEM 3310 based EG (or was it a dual EG) that had a couple of 
different modes. One of those modes involved a second VC Decay stage which 
decayed to the sustain level. I remember this as having a fair number of 
components even with the 3310. I could snail you a copy of the schematic and 
docs if it ain't already up somewhere.

Good idea, Ken!
